What is standard practice to stop and start orion services

I feel like Orion is pretty robust about not being too worried about specific services.   I've killed services 100 different ways over the years, the main trick being that if you have HA you need to disable that first to avoid having it try to bounce you over to the backup server. 

True, want to know sequence that is first do i need to stop services from APE, AWS, HA and last Main poller then as per recomendation needs to reboot server, isn't it?

Yup, if that is what you are looking for then you are correct, in older versions we use to follow the same procedure.

Stop services on APE's and AWS and finally stop the services on Main poller.

In your case

1. stop APE/AWS services

2. Then stop HA

3. Then stop services on Main poller 

=========================================

And if you want to start the services then it would be:

1. Start services on Main poller

2. Start services on HA Server 

3. Enable HA

4. Start services on APE

5. Start services on AWS

Cool, thanks for sharing thought and experience.

Cool, thanks for sharing thought and experience.

Just added start sequence as well, hope it helps.

good, thanks for help

Just want to check that while stopping services do i need to stop" dependencies" & "websites services" too?
